I tried with this gui but it is giving an error as -

Attempt to reference field of non-structure array.

Error in serial_GUI_noICT>connectButton_Callback (line 208) serPortn = get(handles.portList, 'Value');

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in serial_GUI_noICT (line 46) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)serial_GUI_noICT('connectButton_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

Could you please help..!

Which MATLAB release are you using?

Are you getting the list of ports, COM1, COM2, and so on?

There was an old release about 5 years ago where you might have to change

   serPortn = get(handles.portList, 'Value');

to

   serPortn = get(handles(1).portList, 'Value');

and probably other places would need changes to. The bug was corrected in the next release (and probably in a service pack as well.)
